For as much success as the Oley Valley girls have had recently, something was missing.

The Lynx have dominated Division III of the Berks Girls Basketball League. They won the 2011 District 3-AAA championship. They even advanced to the Elite Eight in the state tournament.

Despite that, the current seniors hadn't won a Berks playoff quarterfinal.

"It's a really big deal for all of us," Nicole Vallely said. "None of us have ever been to the Sovereign Center. We pushed really hard to get it."

Now the Lynx are on their way.

Vallely scored 13 of her game-high 19 in the first two quarters, leading Oley to a 17-point halftime lead and a 54-39 victory Saturday against Berks II runner-up Muhlenberg. Loryn Grieb had 16 points and seven rebounds, and Jasmen Clark supplied 12 points and eight boards at Reiffton.

Oley (22-0) will face Berks I champion Reading High Tuesday at the Sovereign Center. Isis Thorpe scored a season-best 29 points in the Red Knights' 65-34 win over Berks IV runner-up Wyomissing. Wilson will meet Daniel Boone in the other semifinal.

"The last three years, we lost to a Quad-A team," Oley coach Mike Clark said. "For a Division III team to beat a Quad-A team, that's big in the Berks County playoffs."

JeanLouise Hornberger scored five of her team-high 10 in the first eight minutes. Jessie Wallace had five points, all in the fourth quarter, and nine rebounds for the Muhls (15-8).

Jasmen Clark hit a jumper with 1:40 left in the first quarter to give the Lynx a 15-3 lead, but the Muhls scored five straight to pull within seven heading into the second. Oley held Muhlenberg to two points in that quarter and led 27-10 at halftime.

One of the top defensive teams in the league, the Muhls limit opponents to 30.3 points per game. Coincidentally, Reading High was the other team to hit 54 against Muhlenberg; no other team has scored more than 38 against the Muhls.

"Loryn and Miranda (Krott) did a great job against (Kerry Kinek) from Allentown Central Catholic," Mike Clark said. "I told them if we limit Wallace's touches and shots, we have an 80 percent chance to win.

"I told Jasmen to be the floor general. She made some good passes and good decisions."

Wyomissing (8-14) went ahead 6-1 two minutes into the second quarterfinal, but the lead dissipated quickly.

Reading (20-1) rolled to a 14-point halftime advantage and led 51-28 after three quarters. Tyeca Reviere had 13 points for the winners, who outrebounded the Spartans 49-21.

Even so, Reading High coach Richie Williams said his team has to be sharper in the semifinals. The Knights were coming off an emotional, physical, division-clinching victory against Wilson.

"With our team, we seem to play down to our competition sometimes," Williams said. "(Wyomissing) wasn't as fast or as strong as us. But you can't do that in the playoffs."
